CHARLES E. MARTIN, OF MANSFIELD, OHIO.

SILO-ROOF.

To all whom it may concern:

Be itknown that'l, CHARLES E. MARTIN, a citizen of the United States of America, residing at Mansfield, in the county of Richland and State'of Ohio, have invented certain new and useful Improvements in Silo- Roofs, of which the following'is a specification.

This invention. relates to certain new and useful improvements in silo roofs and the primary object of. the invention is to'provide a roof which permits the space between the top of the silo and the roof to be utilized for storage purposes.

It is well known that in ordinary silo structures, the space between the top of the silo and the roof cannot be utilizedfor storage because such space is inaccessible and .no provision is made whereby same can be' filled, thus resulting in reduction of the silo capacity. 7

It is further well known'that the contents of the silo sink more or less, especially if the silage has not-been tightly packed, therefore by providing means to permit easy and convenient access to the normally unfilled top of the silo, the silage may be packed tightly, and the space completely filled, thus materially increasing the capacity of the silo.

In brief the invention resides in the formation of an opening in the top part of the roof, and in the provision of a hoodto cover the opening, with means to support the hood in different open positions.

Further and other objects will be later herein set forth, and manifested in the course of the following description.

In the drawings: Figure 1 is a perspective View of the roof showing the hood in open position; Fig. 2 is a centralvertical sectional view of Fig. 1; Fig. 3. is a fragmentary elevation of the hinged cover in open position taken on the line 3 3 of Fig. l; and Fig. 4 is a section taken on the line H of Fig. 8.

The silo is designated 1 in the drawings and has a roof 2 preferably of frusto-conical formation, the roof being composed of a series of tapered corrugated sections attached at their lower ends by means of clips 3 to the silo body and having their upper ends resting against an angle-iron ring 4 and secured to the latter by means of flexible straps 5 which are wrapped around the ring. 4

Specification of Letters Patent. P t nt d e 22; 1916 p Application filed December 18, 1914. Serial 110.87%,991.

Angle-iron legs 6, 7, and 8, are utilized as a means of support for the ring 4 and the.

roof structure as a whole, these legs having a tripod-like relationship and being connected at their upper ends to the ring and at their lower ends to the silo body, as depicted in Fig. 2 of the drawings.

The ring ahit will be evident, bounds or defines the opening which provides an inlet to the silo roof, which inlet is closed by a hood 10 that is constructed as follows: An

outer angle-iron ring 11 is provided and connected to an inner anchorage ring 12 in spaced relation thereto by means of spacing sleeves 13 and bolts 1a. A series of corrugated tapered sections comprise the hood proper lO and are provided with flexible ties 15 which latterare hooked or bent to Hinges 20 are employed to hingedly connect V the hood to the ring 4. In order to adjustably support the hood 7 in varying open positions, a pair 'ofbar's or rods 21 and 22', are provided,.the bars being pivotally attached at theirupper ends to brackets 22 and 23 which latter are secured to the brace 17 the latter thus serving not only as a brace, but as a means of connecting the bars or rods 21 and 22 to the hood.

The legs 6 and 8 which act to support the ring 4 and to brace and strengthen the roof 2 also perform the function of adjustably supporting the lower ends of the bars or rods 21 and 22 for which purpose the legs 6 and 8 are provided with a series of apertures 25. which receive pins 24 that are removably connected to the lower ends of the bars or rods 21 and 22.

hen the hood is in closed position,'rings 11 and 12 excepting the horizontal web of 11 engage or are received within the ring 4, while the horizontal web of the ring 11 extends .over the ring 4 and engages the horizontal web of the latter, thus acting to restrict the extent of downward movement of the hood. f

From the above it will be apparent, that an inlet to the silo is provided at thevery enable the hood to be easily raised or lowered by grasping one rod in each hand, since the rods are located equidistantly on opposite sides or" the hingew20.

What is claimed is:

1. In a silo, a roof of frusto-conical form, a hood composed of an inner anchorage ring, an outer angle-iron ring spaced from the anchorage ring, and secured thereto, a ventilator above said rings, roofing sections secured to the ventilator and engaged with the outer ring, ties connected to the sections and with the anchorage ring and being en-- gaged in part in the space between said rings, and means to hingedly connect the outer ring to the silo body.

In a silo, a cylindrical body, a frustoconical roof, a ring at the top part of the roof, a hood hinged to the ring a ring carried by the hood and adapted to be received within the ring secured to the roof, braces for the roof, and rods hinged to the hood at one end and adjustably connected to the braces at their oppositeends.

in a silo, a roof of frusto-conical form,

an angle-iron ring bounding the edge of the opening at the roof top, and a hood hinged to the ring carrying a ring that is adapted to fit within the angular iron ring of the roof.

e. In a silo, a frusto-conical roof, a hood. hinged to the roof, said hood being composed of inner and outerrings and sectionssecured to the inner'ring, braces-tor.

for the opening including inner and :outer spaced concentric rings,- means to a rlgldly; connect the rings, roofing sections seated on,

the outer ring, and means between the sections and rings for securing the sections to a the latter, said securing means extending in part in the space betweenthe rings.

6. In a silo, a body, a roof on the body formed with a top opening, a hood for said opening including an outer angle-ironring' and an inner ring connected thereto in:

spaced relation, braces seated on top of the horizontal web of the, angle iron ring and.

secured to said web, roofing sections seated on the said web, means to secure the sections 1 to-the inner rmg disposed in party1n1the space between the rings, and means to hingedly connect the anglenon ring to the roof.

In testimony whereoi I ailiX my signature in presence of twowitnesses.
